not only that, but on a windows host on which i had
installed the 8.3 client and server software, when i
uninstalled the server leaving the client software behind,
the client software was no longer complete and couldn't
be used (i.e. python's pygresql module failed to load
even though libpq.dll was there because something else
wasn't there). i had to rsync files over from another
host that had only had the client software installed.

Ouch. The installer is not not properly tracking the sharing of DLLs between components.

The easiest way to just get libpq and the
supporting libraries would be from the tarball distros:

Just extract, and grab the DLLs.

thanks but no thanks. i can see where this might lead.
i don't know what files are needed and what ones aren't.
it probably won't just be the dlls that are needed and
i'll waste half a day experimenting to see what's really
needed. plus it only helps me. it doesn't help anyone else.

Dependency Walker (depends.exe) from dependencywalker.com takes care of that. It really is trivial. However, I agree that it's a cludgy way to do things that shouldn't be necessary.

It'd be good to see a simple MSI installer of the client libs. The Pg server installer could always just bundle the client lib installer, but permit it to be distributed separately as well. That'd save on install complexity and size as well.

EnterpriseDB are currently handling the creation of the binary installers for PostgreSQL. I've been talking with them about some other installer issues (where the interferes with system libraries on Linux) too, so hopefully they'll be doing some work on their installers soon. Maybe they can look at splitting the client library installer into a separate package too.

Dave: Are there sources available for the EnterpriseDB installer/packaging system? I'd like to get into the linux library path patcking problem myself, since nobody at EDB seemed to be interested in the issues when discussed on -general last week.

Craig, we always hear to what the community says as that will help us improve the installer a lot. We have already committed a fix as per the discussion and are in a process of verifying the changes and will be hoping to release it very soon.
